[0029] During train operation, foreign objects may intrude into the road ahead, or geological disasters may occur that prevent the train from operating normally. Alternatively, if foreign objects are discovered but the train is traveling at high speed, it may be unable to respond quickly, resulting in low safety.

[0030] To improve the safety of train systems, this invention proposes a text message sending device for use in train systems to detect foreign objects in the direction of train travel and send a corresponding text message to the target device to indicate the presence of the foreign object.

[0031] It is understandable that the SMS sending device 10 can be installed at the front of the train or at a key location along the track. Installing the SMS sending device 10 at the front of the train allows for direct and effective monitoring of obstacles in the train's direction of travel, real-time foreign object detection, and rapid response to avoid collisions. Installing the SMS sending device 10 at key locations along the track (such as tunnel entrances, near bridges, or geologically unstable areas) allows for monitoring of potential hazards from a ground perspective, providing an additional layer of safety, and promptly notifying approaching trains to take preventative measures upon detecting anomalies. Alternatively, the SMS sending device 10 can be installed both on the train and at key locations along the track to enhance safety.

[0032] It is important to note that these devices, positioned at key locations along the track, can send corresponding text messages to the target equipment before the train reaches the designated location, allowing for advance warning and timely intervention. This way, foreign objects may only be detected when the train reaches the correct location, reducing situations where emergency evacuation is impossible due to excessive speed.

[0033] In one embodiment, such as Figure 1 As shown, the SMS sending device 10 includes a detection module 100, a main control module 200, and an SMS sending module 300.

[0034] In this embodiment, the detection module 100 outputs a detection signal after detecting a foreign object in the direction of train travel. It is understood that the detection module 100 can be a sensing unit used to monitor abnormal objects or hazardous environments at key locations along the train's direction of travel or the track in real time. Optionally, the detection module 100 integrates multiple sensors, such as millimeter-wave radar, lidar, visual cameras, or infrared detectors, to identify foreign objects, such as falling rocks, landslides, or obstacles, through multimodal data fusion technology.

[0035] When an anomaly is detected, the detection module 100 generates a detection signal. To ensure a low false alarm rate, the detection module 100 may embed a dynamic threshold adjustment function at the algorithm level, such as adaptively optimizing the detection sensitivity according to weather conditions (rain, snow, fog), while also supporting edge computing to reduce latency.

[0036] In this embodiment, the main control module 200 is electrically connected to the detection module 100. The main control module 200 is used to call external SMS information based on the detection signal and output corresponding control signals. It can be understood that the main control module 200 is responsible for signal processing and logic control. After receiving the trigger signal from the detection module 100, the main control module 200 first verifies the signal and then calls the preset external SMS information database.

[0037] In one feasible implementation, upon receiving an HTTP request from the detection module 100, the main control module 200 first parses the risk data in JSON format and performs multi-dimensional verification (such as data integrity and risk threshold judgment). Then, it calls the built-in strategy library to map the risk level to specific actions: low risk generates an early warning log, while medium and high risk triggers an SMS sending process.

[0038] Optionally, the database of external SMS information may include train location codes, track section IDs, or preset emergency plan codes, and may also include target device codes, SMS receiving numbers, etc.

[0039] Optionally, the main control module 200 is used to output corresponding AT commands to the SMS sending module 300 based on external SMS information, so as to control the SMS sending module 300 to send SMS messages.

[0040] In this embodiment, the SMS sending module 300 is electrically connected to the main control module 200. The SMS sending module 300 is used to send corresponding SMS messages to the target device according to control signals. It can be understood that the SMS sending module 300 acts as a communication execution terminal, used to convert the AT commands of the main control module 200 into SMS messages. The SMS sending module 300 accesses the cellular network through a built-in 4G / 5G module, supporting multi-band adaptive switching (such as automatically increasing transmission power to address signal attenuation in tunnels), ensuring communication reliability in complex geographical environments. When it receives an AT command from the main control module 200, the SMS sending module 300 first performs syntax verification (to prevent abnormal commands from causing module deadlock), and then sends structured alarm information (such as "Level 2 rockfall risk detected 50 meters west of G325 tunnel, speed limit recommended 80km / h") to a preset number or a preset target device through the operator network. Optionally, the preset number can be obtained from external SMS information, and the content of the SMS message can also be obtained from external SMS information.

[0041] Optionally, the SMS sending module 300 also has a retransmission mechanism: if SMS sending fails, it automatically attempts to switch APN (Access Point Name) or enable the backup SIM card slot, and at the same time reports the sending status to the main control module 200 so that the main control module 200 can record audit logs or start a backup communication channel (such as a satellite link).

[0042] It is important to note that the SMS sending module 300 is primarily used to send specific information (such as foreign object detection alarms) in the form of SMS messages to preset target devices (e.g., train control center, maintenance personnel) according to instructions from the main control module 200. When the SMS sending module 300 receives control signals (such as AT commands) from the main control module 200, it generates and sends SMS messages according to a predetermined format and content. Therefore, unlike traditional two-way communication devices, this SMS sending module 300 does not have the ability to receive any instructions or data from the outside world (whether via SMS or the network). Thus, even if an attacker attempts to send malicious instructions by forging SMS messages or exploiting network vulnerabilities, the SMS sending module 300 will not receive these instructions, thereby avoiding the risk of unauthorized control and improving the security of the train system.

[0043] On the other hand, the main control module 200 obtains external SMS information from the external storage system, which can greatly simplify the SMS sending process, enabling the system to quickly and efficiently send SMS messages with different content to multiple recipients. At the same time, it can also reduce the workload of the SMS sending device 10, as it does not need to store relevant information, and further ensures that it will not be maliciously attacked. Even if it is maliciously attacked, it will be unable to obtain valid data (such as train information or telephone information).

[0044] In one feasible implementation, the main control module 200 communicates wirelessly with the external storage system. After receiving a detection signal, it matches the detection signal with the corresponding external SMS information in the external storage system and obtains it. Then, it outputs the corresponding control command to the SMS output module according to the external SMS information to output the corresponding SMS to the corresponding number or target device.

[0045] In one embodiment, the main control module 200 includes a wireless communication module electrically connected to an external storage system, and the wireless communication module is used to call the external SMS information in the external storage system.

[0046] Optionally, the wireless communication module includes one or more of a Wi-Fi communication component, a Bluetooth communication component, a 4G network, and a 5G network. Of course, it can also be other modules besides those mentioned above, and there is no specific limitation here.

[0047] Understandably, the external storage system is a data storage system independent of the SMS sending device 10 on the train, and can be located in the cloud or at a ground base station. This system stores various necessary information, including but not limited to train location codes, track section IDs, preset emergency plan codes, target device codes, and SMS receiving numbers.

[0048] In one feasible implementation, when the detection module 100 detects a foreign object or potential hazard, it sends a detection signal to the main control module 200. Upon receiving the signal, the main control module 200 accesses the external storage system via its built-in wireless communication module to retrieve corresponding external SMS information. This information may include preset SMS templates for specific situations, contact information for relevant personnel or departments to be notified, etc. The main control module 200 fills in or adjusts this information according to the actual situation, and then instructs the SMS sending module 300 to send the customized warning SMS to the pre-set target device.

[0049] In one embodiment, the main control module 200 is electrically connected to the SMS sending module 300 via USB. It is understood that the main control module 200 can send commands (such as AT commands) to the SMS sending module 300 via the USB interface to control the SMS sending module 300 to perform specific operations (such as sending SMS messages).

[0050] In one embodiment, the SMS sending module 300 is powered via a 9V-36V adapter, and / or the main control module 200 is powered via USB-Type-C. It is understood that the SMS sending module 300 is powered via a 9V-36V adapter, while the main control module 200 is powered via USB-Type-C, or both may use their respective power supply methods to meet different scenario requirements. This design combines the power consumption characteristics of the two modules with the actual application environment: the SMS sending module 300 supports a wide voltage input (9V-36V), enabling flexible adaptation to DC power supplies on trains or power supply systems for equipment along the track, ensuring stable operation under complex power supply conditions; while the main control module 200 uses USB-Type-C power supply, leveraging its versatility, reversible plugging and unplugging capabilities, and simultaneous data and power transmission advantages, facilitating on-site debugging and temporary deployment.

[0051] In one embodiment, such as Figure 2 As shown, the detection module 100 further includes an image acquisition module 110 and an analysis module 120. The image acquisition module 110 is used to acquire image information corresponding to the presence of foreign objects in the direction of train movement. The input terminal of the analysis module 120 is electrically connected to the output terminal of the image acquisition module 110, and the analysis module 120 is used to output a corresponding detection signal based on the image information.

[0052] Understandably, the image acquisition module 110 is responsible for acquiring real-time image information of the train's direction of travel, capturing images of potential foreign objects or abnormal environments through cameras or other visual sensors. Subsequently, the image information is transmitted to the analysis module 120, which uses image processing algorithms (such as edge detection and target recognition) or artificial intelligence technologies (such as deep learning models) to analyze and judge the images, identifying the presence of foreign objects and their potential threats. Once the presence of a foreign object is confirmed, the analysis module 120 generates a corresponding detection signal and outputs it to the main control module 200, thereby triggering subsequent early warning or emergency response procedures. This not only improves the accuracy of detection but also enhances the system's adaptability to complex scenarios.

[0053] In one embodiment, the image acquisition module 110 includes one or more combinations of a laser scanner, radar, and infrared sensors to achieve multi-dimensional perception and accurate detection of foreign objects in the direction of train travel. The laser scanner provides high-precision distance measurement and 3D environment modeling, suitable for identifying the shape and location of obstacles; radar is used to detect distant targets and maintains high reliability under adverse weather conditions (such as rain, snow, fog, and haze); the infrared sensor, by sensing the thermal radiation of objects, can effectively identify living organisms or high-temperature objects at night or in low-light environments. By using these technologies individually or in combination, the image acquisition module 110 can fully utilize their respective advantages, overcome the limitations of a single sensor, and thus improve its adaptability to complex environments and detection accuracy.

[0054] In one embodiment, the main control module 200 is an Orange Pi control board, specifically the Orange Pi R1 Plus LTS model. The Orange Pi R1 Plus LTS features a high-performance quad-core Cortex-A53 processor, providing powerful data processing capabilities, enabling efficient analysis of data from the image acquisition module 110 and rapid response. This Orange Pi control board can be equipped with various interfaces (such as USB and RJ45 Ethernet ports) for seamless integration with the SMS sending module 300 and other external devices. It also supports Gigabit Ethernet and Wi-Fi 802.11ac, ensuring stable and fast network communication, which is beneficial for data exchange with external storage systems and sending early warning information.

[0055] In one embodiment, the SMS sending module 300 is specifically a data transmission unit, model TAS-LTE-363. TAS-LTE-363 is an industrial-grade data transmission device supporting 4G LTE networks, featuring high stability and wide coverage, ensuring communication continuity in complex geographical environments (such as tunnels and mountainous areas). It has a built-in multi-band adaptive switching function, automatically adjusting the frequency band according to signal strength, thereby reducing the impact of signal attenuation on data transmission. Furthermore, this data transmission unit supports the standard AT command set, facilitating seamless integration with the main control module 200 and rapidly sending warning information to target devices via the cellular network. Its compact design and low power consumption also make it ideal for deployment at critical locations along trains or tracks, further enhancing the real-time performance and reliability of the SMS sending system.

[0056] This utility model also provides a text message sending system for use in a train system, the text message sending system including the text message sending device 10 as described in any of the above.

[0057] It should be noted that this SMS sending system includes the SMS sending device 10 as described above. The specific structure of the SMS sending device 10 is as described in the above embodiments. Since this SMS sending system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0058] It is understandable that the SMS sending device 10 can be installed at the front of the train or at a key location along the track. Installing the SMS sending device 10 at the front of the train allows for direct and effective monitoring of obstacles in the train's direction of travel, real-time foreign object detection, and rapid response to avoid collisions. Installing the SMS sending device 10 at key locations along the track (such as tunnel entrances, near bridges, or geologically unstable areas) allows for monitoring of potential hazards from a ground perspective, providing an additional layer of safety, and promptly notifying approaching trains to take preventative measures upon detecting anomalies. Alternatively, the SMS sending device 10 can be installed both on the train and at key locations along the track to enhance safety.

[0059] It is important to note that these devices, positioned at key locations along the track, can send corresponding text messages to the target equipment before the train reaches the designated location, allowing for advance warning and timely intervention. This way, foreign objects may only be detected when the train reaches the correct location, reducing situations where emergency evacuation is impossible due to excessive speed.
